The status of fundamental physical constants is discussed. The nature of fundamental physical constants is cleared up, based on the analysis of the Boltzmann constant. A new definition of measurable values, 'mathematical' and 'physical' numbers and f

A novel method of low-melting metal micropowders fabrication is proposed. Low-melting alloy is dispersed into a polymer matrix under extrusion processing. Then the polymer matrix is dissolved and metal powder is removed from the suspension. Thus low-

Tunable CO2 and non-tunable CO2 lasers were used for the irradiation of thin polypropylene films. The wavelength of the IR radiation was adjusted in such a way that it coincided exactly with the absorbance peak in the spectrum of the polypropylene pa
